To (17/ u'luml 1'1: IHU'I/ concern tie it known that l. (lnonon W. Final), a citizen o'l.the United States, residing at. North ltranch. in the county of Somerset Specification of Letters Patent.

Application filed March 10.

and State ot New Jersey, have invented a i new and useful Milk-Retarder, of which the following is a specification.

The present invention appertains to an apparatus for h ating or cooling milk, and aims to provide a novel and improved device of that character.

it is the object of the present. invention to provide a casing or cylinder through which the milk is adapted to be passed. and novel means within the casing or cylinder for retarding the [low ot the milk therethrough.

Another object ol the present invention is to provide in combination with the retarding means within the using or cylinder. unique means for spreading or ditl'using the milk as it ttows through the casing. whereby the heating or cooling of the milk will be. rendered mere uniform and eticctive.

The present invention also contemplates the provision of an apparatus ot the nature indicated. wherein the casing or cylinder is provided with a plurality of compartments, through which the milk is arranged to tlow successively. means being provided whereby any or all ot' the compartments er chambers may be d 'ained. and whereby milk may be made to flow through one or more of the compartments. as desired.

It is also within the scope of the present invention to provide a milk eooling or heating appar: tus 'ot the charznttcr above intimated. whieh will be improved generally in its construction. whereby the utility of the apparatus will be enhanced.

With the t'eregoing and other objects in view which will app proceeds, the invention resides in the combination and ar 'angement of parts and in the details of eonstiruction hereinafter described and claimed. it I being understood that changes in the precise embodiment of the invention-herein disclosed ean be made within the scope ot what is claimed without departing From the spirit of the invention.

The invention has been illust 'ated in its preferred embodiment in the accompanying drawing. wherein-- Figure l is a longitudinal vertical section ot' the improved apparatus, portions being t' ken away, and portions being shown in 2- is an en urged cross section of *a as the description Patented J inlet), 1914. 1314. Serial N0. 823,828.

the apparatus. Fig. 3 is an enlarged tragmental sectional detail.

ln carrying out the present invention, there is provided a horizontal casing orcylinder I. which is provided with outer and inner walls 2 and 3; respectively, whereby the interior of the casing may be jacketed with water or with an insulating agent. The top of the casing t-is removable, so as to provide a cover or lid 4. I

The casing or body I is preferably suppi rted in an elevated or raised position, by means of U-shaped hangers- 5 in which the caring l is slung or seated. the upper ends of the hanger 5 engaging through the ceilings or overhead supporting structure (3 and having nuts or other retaining elements 7 engaged to their upper ends. Notched seat elements 8 are prete'ably secured to the sides and bottom of the casing l, to engage over the hangers 5 for maintaining the as ing against longitudinal movement within the hangers. but enabling the easing to be rotated within the hangers, when necessary or desirable.

The interior of the into a plurality or chambers by compartments 'asing 1 is divided or a series of compartments means of partiticns 9, the or chambers 10 being arranged in a longitudinal series, and being closed one from the other. 1) the cover t which tits tightly over the upper ends of the partitions. The joints between the. cover and the sides and ends of the casing 1. as well as the partitions t), are preferably ground, to prevent leakage.

.\n inlet or supply pipe 11. which extends from the pasteurizer -or pump. ektends through one end of the casing 1 adjacent the upper end of the corresponding compartment or chamber 10. whit. a discharge or outlet pipe leading to the cooler, has a branch 13 engaged through the other end of the 'asing 1 adjacent the upper end or mouth of the correspomling end compartment 10. a valve 1% being preferably interposed between the discharge pipe 12 and its branch I"). It is desirable to attach a suitable recording gage 15 to the casing of the valve 14. whereby the gage may be observed by the attendant.

The coupling ttL which may be provided with a valve. if desired. is interposed in the t'tischarge or outlet pipe 12, and has attached thereto, a drain pipe 17, extending longitudinally a in the bottom portion t i at too casing 1, between the inner and outer walls thereof, The drain pipe 17 extends under the compartments 10, and is provided at spaced points with upstanding branches 18, one for each compartment 10. The branches is are preferably arranged centrally of the compartments 10, and have their upper or free ends enlarged, as at, and engaged through the inner Wall 3 of the casing 1, so as to communicate through the bottoms of the compartments 1.0.. The enlarged pzrtions 19 provide sockets or counter bores for the purposes which will. here ina-ftcr appear. The pipe 17 is further provided with depending branches F20 helo'iv and alining with the upstanding hrancos l8, and engaging through the outer Wall or bottom of the casin v Caps'or closures 21 are seated against the lower ends of the branches 20, and are retained in place by means 01" the flanged. retaining nuts 29, extended over the lower or free ends of the branches The caps are provided with depending tubular cxtensions 23.

Plugs or valves disposed snugly Within the upstanding branches 18 of the drain pipe 17, below the enlarged portions 19, and have their bottoms inclined, as at Stems or spindles 26 are slidahlc through the caps 21 and their tubular can tensions orguides 23, the upper ends of the stems or spindlos terminating directly below the inclined bottoms of the plugs or valves 24:, and the lower ends of the said stems depend or protrude from the guides 23, in order that the stems may be raised by hand. The stems 26 are provided with on largements 27 normally seatable upon the caps 21, for supporting the stems or spin tiles in place, but enabl ng them to be readily raised as desired. The stems or spin-- dies 26 provide means tor releasing); or lib crating the plugs or valves 24, as will hereinafter appear.

A nipple i528 engaged through each oi" the partitions 2) between the compartments 10, adjacent the upper ends of the partition, and an angular or L-shaped inlet pipe 29 is disposed within each of the compartments 10. The upper arm of the inlet pipe within the primary compartn'ieiit 10, is connected to the end of the supply pipe 11, while the upper ends of the other pipes 29 arcconnected to the respective nipples by. the means of ordinary union couplings lid: The other arms of the inlet pipes 29 r pend centrally within the compartments .113, and are provided adjacent their lower ear-- trcmities with lateral ln'anchcs or arms 33], arranged longitudinally ol the casing, and directly adjacent, hut spaced slightly from, the bottoms of the compartments. The lower rcniitics or end piirtions of the depending a of the nines 32$) are normally received by the enlarged portions or sockets 19 of the upstanding hraiiches 18 of the discharge or drain pipe 17, to assist in supporting the pipes 29 and in maintaining them. against accidental displacement Within the compart 7o merits. 'lhe-hranches or arms 31 of the inlet pipes 529 have their free ends terminatingdirectly adjacent, hut spaced slightly from, the partitions 9, and are provided with longitudinal slots 32in their bottoms. The lower slots of the branches 0' arms 31 extend into the lower portion of the depending arms of the pipes 29, as clearly seen in Figs 9. and 8.

' it transversely coi'icavcd spreader or difit 33 is arranged within each compartment 1.0, and (Jo-extensive with the branches 31 of the corresponding pipe 29, the median portion of the spreader 33 being attached to the said branches 31. The spreader 33 in each compartment is aper" tut-ed or perforated, and is carried by the branches 31 of the pipe 2%, as will he evident, The spreaders are spaced above the bottoms of the compartments l0 and are preferably concentric therewith.

In practice, the supply and discharge pipes Hand 12, respectively, of theprcsent apparatus, are connected by means of hose or other flexible connections, with the pastuerizer or pump, and the cooler, rcspectively. The flexible connections will enable the casing or body 1 of the apparatus to be rotated or oscillated within the hangers 5, for purpose of. cleaning and sterilizing the 0 present apparatus as will hereinafter more fully appear. It is prefc able to provide a casing, 1 with five o the compartments 10, although the number of the compartments may he increased or diminished, according to the circumstances. It has been found, however, that with the present apparatus, it requires approximately four minutes of time for the milk to flow through one of the compartnienls, wl'ierchy when five compartments are utilized, it will take approximately twenty minutes for the milk to trave se the present apparatus, which is the i .u.il practice. In operation, when the milk is fed, either by gravity, or under pressure, through the supply pipe ll, the same will fiow into the first compartment 10 through the primary inlet pipe or tube 29, which is connected j directly to the supply pipe 11. Then, as the first compartment becomes filled, the milk will t 1 high the first nipple and the cert" 1e 2? into the second comlg understood that under or oar. dinay l i one, the stoppers or valves 24 will. std, to n-event the discharge of the milli: tl'irough the pipe 17. Thus, as the mill: is admitted into the casing 1, thesuccessivo compartments ll} will he filled and thirdly, the mill; will be discharged through (ill the outlet or discharge pipe 12. Now, as the milk lion's. down eaeh ot' the pipes 35, the same will be divided and passed into the banehes 31 of the said pipe. the brunt-hes 3t preterably being of asmaller diameter than the body or main portion ot the pipes 95 From the'ln'an hes ill. the milk will flow downwardly through the slots 32 and upwardly around the spreaders or dill'nsers 33. The Spreaders 33 are a pertnred or perto ated to permit the milk to des end there through, thereby enhancing the ditl'usiag funetion ot the spreaders. it will thus we obvious. that; the milk being diseharg l through the lower slots of the branehes I and passing around and through the spreaders 3 3, will heroine thoroughly mixed or dil fused. to faeilitate the heating or eooling of the milk, whieheveris the ease It is evident that either cold or hot, water may be eirqulated through the jaeket ol' the et ll easing i, it being the ohjeet ot' the present lltYtlltititl. however. to provide an apparatus for ell'eetirely heating and assimilating the milk. it. being evident that when the easing 1 is heated the milk being heated. and dilfused within the eompartnwnt, will beroine thoroughly and uniformly heated, to the ends desired. It is also possible to plaee an insulating agent within the jaeket ol' the easing, whereby when heated milk is sup lied into the easing, the same may be retained at. its original or normal temperature. When it. is desired to employ less than the whole number of the compartments or ehainbers 10, the desired number of taimpartments nuiy be cut out, by rel asing one or more of the stoppers or plngs'il. whieh will enable the mi k to escape through the drain pipe 1? to the outlet or diseharge pipe 12. without passing thl'ongh the eompartnients ltl beyond the stopper T'Zl whirh has been opened or liberated. ".io openor release one of the stoppers or valves ll, it is nterel neeessary to raise the eorresponding stem or spindle Bit upwardly whereby the upper end of the stem engaging the lltt'llltttl bottom 25 ot' the stopper will raise or slide the stopper. ll

will be erident. that as the stopper is raised. one side thereol' will be released first. from the upstanding brain-h 1S ol the pipe 1?. whereby the stopper will tilt within the eu larged or soeketed portion ll) so as to open the pas age through the braneh l3 tor the purposes noted.

been opened, eonnnnnit'ation will be establlhen the stopper 2t has lished direetly trom the eorresponding pipe 29 through the drain pipe 1T. Thus.

when it is desired to have the milk tlow through only one ot the eompartmenta t0. the stopper 2 t of the set-end eompartnient 10 is opened, whereby the milk will be prevent? ed from flowing through the seeond and sueeessire coinptn'tinents. Similarly when the stopper of tho thircl compartment is opened,

milk will llow throu gh the first and seeond eompartnients. but not through the third one. in order to d 'ain the eoinpartments lt alter the eonipletion ol' the eooling or heating at the milk. the sneeessire st ppers Bl ot' the eompartnients are opened. whereby the compartments may be drained through the drain pipe 1T. one at a time, or in regular order.

The present tltYltG may be readily el aned and sterilized alt-er the eoinpartments have been drained. by removing the eo\et 1, and then rotating the easing t to enable areess to be had to the several eompartment it is then an easy matter to l'tltitlH the pipes il and the spreaders l-fl earried thereby. by

opening the union eonplings Pill. The lower extremities ol' the pipes 29 may be readily slipped out ot' engagement with the endrain pipe lT. .Xl'ter the pipes il have been witlnlrawai. the stoppers ill may be remored. as well as the stem ill. it' desired. 'l he eon] partineuts and pipes. and other parts ol' the apparatus may be readily eleaued and ster lixed. and alter the same are eleaned. the parts may be readily assembled for a new operation.

The present apparatus is sanitary or bygienie. and is ot' advantage in other obrions respeets as will be ai iparent from the loregoing taken in eonneetion with the drawing.
